PERMANENT HAIR WAVING APPARATUS Original Filed June 28, 1950 Fig.1 Fig-2 Patented Dec. 27, 1932 UNITED STATES PATENT OFFICE FRANZ XAVER MAIER, F MUNICH, GERMAN Y PERMANENT HAIR WAVING APPARATUS Original application filed June 28, 1930, Serial No. 464,568, and in France November 15, 1929. Divided and this application filed November 17, 1931.

I have filed applications as follows: France Nov. 15, 1929; Great Britain June 18, 1930, and Denmark Aug. 12, 1931.

This invention relates to permanent hair waving apparatus for forming fine waves Without injuring the hair and without any unpleasant effect on the scalp.

The present invention relates more particularly to means for heating the hair after it has been applied to a waving instrumentality such, for instance, as is disclosed in my application for Letters Patent of the United States, filed June 28, 1930, Serial No. 464,568, of which this application is a division.

It is an object of this invention to provide a heater having means for embracing or partially embracing the wave forming device with the hair applied thereto, the said wave forming device being generally known and hereinafter referred to as a hair winder.

It is a further object of the invention to provide means for manipulating parts of the heater during its application to or removal 1 from the hair winder, and also for including means for controlling an electric circuit for the electrode or heating element.

With the foregoing and other objects in view, the invention consists in the details of construction, and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.

In describing the invention is detail, reference will be had to the accompanying drawing forming part of this application, wherein like characters denote corresponding parts in the several views, and in which Figure 1 illustrates a view in side elevation of a heating device embodying the invention;

Figure 2 illustrates an end view thereof; and

Figure 3 illustrates a sectional view of the hair winding bobbin and parts associated therewith.

In the drawing, a core n is shown, which is preferably of the usual bobbin form but roughened over a part 0 of its surface in order to provide a good seating for the hair which is wound around it, and the wound hair is embraced by a packing consisting of rIJ Serial No. 575,655.

an inner sleeve 1" which encloses the hair, and by superimposed layers such as'a cotton wool lining s and an outer protective waterproof cover t. The sleeve 9" serves to make the hair soft and pliant and preferably the parts 1', s, t of the packing are connected so as to form a single unit. A- clip o which consists of two thin hinged metal strips serves to hold the packing r, s, t and the hair wave contained in the packing together.

A heater is placed on each hair Winder with its packing.

The heating element, in the present embodiment of the invention, consists of a semicircular metal casing to containing the electrode or heating resistance and this is adapted to fit over the hair winder and the packing. The casing to is provided with a handle formed by the parts w, 1 which at the same time serve as shields for the terminals for the electric current. The plate 00 is preferably rigidly attached to the casing to and provided with a fiat cap y, back of which the conducting cor-d a is arranged. The plate so is insulated from the casing to and the conductor by means of an intermediate layer 8 of asbestos or other suitable material. A spring pressed clamping lever 10 having a press button 11 is hinged at 9 to the plate w and a projection 12 of the lever 10 engages the winder packing below the casing to for maintaining the assembled parts in position.

I claim:

1. In a hair curler, a bobbin shaped core, a unitary packing surrounding said core including an inner sleeve for enclosing the hair and an outer waterproof covering, said cov ering and sleeve having a fibrous layer of cotton like material interposed between them, a clip engaging the packing against its edges, a semi-circular metallic casing fitted over a portion of the packing and containing a heating element, a handle fixed to the casing and projecting upwardly therefrom, wire terminals connected to the heating element and enclosed in said handle, said handle consisting of a member formed to receive said terminals, a cover plate separated from said member by a heat insulating layer, a lever pivoted to the cover plate and having an inwardly directed end engaging the packing below a longitudinal edge of the casing, and

a spring urging said lever to engage said packing.

2. In a hair curler, a bobbin shaped core, said core having a roughened central portion to prevent slipping of the hair when in contact with the bobbin, a unitary packing surrounding said core including an inner sleeve for encloslng the halr and an outer waterproof covering, said covering and sleeve having a fibrous layer of cotton like material interposed between them, a clipengaging the packing adjacent its edges, a semi-circular metallic casing fitted over a portion of the packing and containing a heating element, a handle fixed to the casing and proj ecting' upwardly therefrom, wire terminals connected to the heating element and enclosed in said handle, said handle consisting of a member formed to receive said termina1's,a cover plate separated from'sai'd member by a heat insulating layer, a lever pivoted to the cover plate and having an inwardly directed end engaging the packing below a longitudinal edge of the casing, and a spring urging said lever to engage said packing.
